Given that the posters at the (censored) “Skeptics Society” forum, including the holocaust controversies camp follower known by the pseudonyms “KentFord9” and “Statistical Mechanic”, have recently been making fools of themselves on the subject of cremation remains, this post may be of use for the purpose of limiting the further spread of idiocy. In an attempt to deny the possibility that postwar deposits of cremation remains (cremains for short) may have contributed to the supply of bone fragments currently to be found on the surface of the camp grounds at Treblinka, they have argued that cremains are “ashes” rather than bone fragments, offering a photo as evidence. As I have already shown, cremation ovens leave sizeable bone fragments, looking something like this:
The more homogeneous appearance of cremation remains as often seen is the result of post-processing. In the case linked above, this appears to have been done with a rotary blade processor. The use of a ball mill or of hand processing would leave rougher remains. It should be noted that customs concerning post-processing of cremation remains vary in space and time (a high degree of processing being more common in the United States than in most other locations, and the rotary blade processor being introduced only in the 1980s), with some cultures favouring unprocessed remains, and even in cases where post-processing is customary it is often possible to request that remains are left unprocessed.
Given this information, it’s easy to see that the argument these anti-revisionists are attempting breaks down completely.
